Ensure Your Database Stays Online, No Matter What

In today’s fast-paced digital landscape, database downtime is not an option. Whether you’re running mission-critical applications, e-commerce platforms, or real-time analytics, your PostgreSQL database must be highly available, resilient, and performant.

At CNS, we specialize in PostgreSQL High Availability (HA) Services, ensuring your databases remain online, scalable, and disaster-proof.

Our PostgreSQL High Availability Expertise

Implementation

We design and deploy robust PostgreSQL HA architectures tailored to your needs, including:

  • Auto-failover setups (Patroni, repmgr, Pacemaker)
  • Multi-master replication (BDR, Citus, PostgreSQL-native logical replication)
  • Geo-replication & disaster recovery (WAL archiving, standby clusters across regions)
  • Cloud-optimized HA (AWS RDS/Aurora alternatives, Google Cloud SQL HA, Azure PostgreSQL configurations)

Management

Proactive database administration to minimize downtime and maximize efficiency:

  • Cluster orchestration & configuration tuning
  • Load balancing & read scaling (Pgpool-II, HAProxy)
  • Automated backups & point-in-time recovery (PITR)

Monitoring

Real-time visibility into your PostgreSQL clusters with:

  • Custom dashboards (Prometheus + Grafana, Zabbix, Nagios)
  • Alerting on critical metrics (replication lag, disk space, query performance)
  • Performance tuning insights (pg_stat_statements, auto-explain)

Maintenance

Keep your PostgreSQL environment secure and up-to-date with:

  • Zero-downtime upgrades (major & minor version updates)
  • Security patching & compliance hardening
  • Storage optimization & resource management

“We appreciated CNS performance during the mission at Ekwateur. CNS was a force for proposals. CNS’ work had a positive impact on the performance of our applications and databases. CNS has always been relevant in their interventions and we have particularly appreciated their investment and ability to dig and go to the end of the subjects. All this in compliance with the deadlines we determine together. We plan to continue utilizing CNS on similar missions.”

“The mission with CNS went very well! From the project to be framing to the deliverable they were very professional and effective. I would not hesitate to call them again if the need arises!”
— Edouard, HIFLOW SAS

“Positive experience. This audit mission made it possible to enlighten us on axes for optimizing the performance of our environment. After an initial phase to pose the expectations and needs in terms of access to work remotely (provide a little time for this implementation phase), the mission was effectively. With exchanges via Gitlab. The audit report is factual, precise and quality. The whole thing has been the subject of a restitution meeting.”
— Stéphane, TotaalEnergies OnTech – CSTJF

“I consulted CNS to audit a server instance with a Apache / PHP in back-end and a Nodejs / Next on the front. He quickly failed to finger problems as well as possible improvements. I recommend without hesitation.”
— Jordan, Plop

“CNS was very effective, sympathetic, communicative and provided clean work and up to our expectations. Thank you so much ! I highly recommend them.”
— Nicolas, Solidarites International
